'21 new and useful linllmving is a spehifioation. i Jill. is a method ofattaching a a, h grenade of thin metal,

joint between said id the burning of its the weltlins; electrodes.

It'll.

meet in two Ctli'P-SlllPEd 1 m A' Wm IllGHlJ. mention 1. 1s opening Csurrounded ncrl Hans" B. The two {pies m rl-3gare l electric weloing".is made of heavier metal. annular flange F at one end richer time. thebody portion of ime, .ltilfi grenade is placer-5. 111 a electrode H. .ihe tube is seated in a corresponoinglyformed recess in an electrode I,with its outer iace bearing upon flange D, as shown m Fig. The

I welding current being established. electrode i is moved downwardly topress the. flange F upon the flange D. Flaufge D becomes fused anddisappears. the melted metal thereof serving to unite the tube andsection A together. The enlarged flange E affords :1 body of metal whichabsorbs sufiicient of the heat to prevent the thin metal of sec tion A.outside of the flange D. from being burned. li e preferably make theflange polygonal in form, so that a wrench may be applied thereto tohol" the grenade during loading and insertion of the fuse.

We claim: v

The method of uniting a fuse tube to a hand grenade of thin metal, whichconsists in forming in a flattened end of said greuaiie an openingsurrounded by an outwsmily turned flange, forming a fuse tube having atone end a surrounding; flange of metal thicker than the body portion ofsaid tube. placing the face of saici tube flange upon said grenadeflange, pressing said flanges together. and establishing a weldingcurrent through them; whereby; said grenade flange heeomes fused and thesaid tube flange uniteo to the fiHiiGflQii end of said grenade.

in testimony whereof We have aifirecl our signatures in presence of twoWitnesses.
